Bug ID: 104396
Summary: [11/12 Regression] Invalid SIMD intriniscs accepted at
-O1 and above after r11-6794-g04b472ad0e1dc93aba
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: accepts-invalid
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
Target: aarch64*-*-*
Take:
#include <arm_neon.h>
void f(int32x4_t *p0, int16x8_t *p1) {
vqdmlal_high_laneq_s16(p0[0], p1[0], p1[1], -1);
}
This should be rejected even at -O1 but after r11-6794-g04b472ad0e1dc93aba, it
is accepted as the builtin is now removed with DCE.
See https://gcc.gnu.org/pipermail/gcc-patches/2022-February/589911.html also.
